Specification of Letters Patent.

Patented June 2S, 1921.

Application filed August 28, 1920. Serial No. 406,674.

To all whom it may concern.'

.Be it known that I, ERNST J. ANTONI, a citizen of the United States of America.

residing at Vhitewright, in the county of Grayson and State of Texas, have invented certain new and useful lmprovements in Cotton-Choppers; and do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, forming a part of this specification.

The principal object of the invention is to make eifective the removal of the cotton plants at intervals from the plant rows upon undulatory surfaces or broken ground as well as upon. level surfaces, and also govern the chopping to the depth of the plant roots.

Second, to enable the choppers to be kept in line with the plant rows, in a divergence of the machine from a direct course of movement.

Third, to effect alternate chopping move ments of the oppositely positioned choppers, thereby permitting the spacing of the plants which are left in the removal of the plants by the action of the choppers.

Fourth, to regulate the distance apart of the choppers, so that selected plants may be left standing and the chopping resumed in the center of the row.

Fifth, to effect a concerted action of the chopper' raising and lowering, rocking and spacing movements, and

bixth, to regulate the chopping to the speed maintained by the machine.

The invention consists in the novel construction and combination of parts, which will be first fully described and then specilically pointed out in the claims.

The machine hereinafter described for chopping the cotton plants in the field, is mounted upon a four wheeled vehicle 10, the vehicle being drawn by animal power or the power from a traction. engine coupled to the draft pole 11.

The body of the vehicle consists of a rectangular frame, composed of parallel channel beams 12 and'lQ, upon the respective right and left hand sides of the vehicle, with the forward ends of which beam are connected integrally the ends of the forward Y 2626Qlwhich are end channel beam 13, and with their rear ends is Vconnected integrally the ends of the rear end beam 14.

Vith the lower surfaces of the channel beams 12 and 12, a short distance rearwardly from the line of the forward end beam 13, is secured rigidly the ends of a transverse beam 15. The forward axle supporting` the forward end of the body of the vehicle consists of a short squared portion 16, directly beneath the transverse beam 15, from the ends of which portion extend outwardly and downwardly bent portions 17-17, their lower ends being` bent outwardly and vhorizontally at 1l'-17, upon which latter portions are mounted the wheels 18-18 respectively. See Fig. 4.' Upon the upper surface of the squared portion 16 of the front axle, is mounted a transverse center plate 19, to which is bolted, by bolts 19.', the inward twisted extensions 11 of the separate draft bars 111 which are bolted to the opposite sides and rear end of the draft pole 11, these bars extending within depressions 16X.y beneath plate 19 in the upper por tion of the axle. i

Upon the upper surface of plate 19, is a circular'flat plate or fifth wheel 20, through the center of which plate 20, and the plate 19 passes the kingbolt 21. See Figs. 3 and 4. Flatbars 23-23 arebolted to the opposite portionsI and lower surface of the transverse beam 15, on the body of the vehicle at theirl upper ends, the` lower portions of which bars extend downwardly and are inclined inwardly and are integral with each other.` and bear upon' the fifth wheel 2O on the plate 19. through which integral portion of the bars 23-23 the kingbolt extends, the said bars 253-428 affording a rigid support Yto the body of the vehicle.

' Thereai.' axle 24 is a straight shaft andV is journaled in the lower end portions of the flanges or bars 25-425. These bars are provided with inwardly extended flanges 25 at their upper ends, which flanges are bolted to the lower flanges of the channel beamsY 12-12, inV a. vertical line with the outer edges of said flanges and at a point on said beain approximately one-fifth the distance forwardly of the line ofthe rear end beam 14.

Upon the outer ends of the shaft or 'axle 24, are mountedV fixedly the rear wheels about one-third larger in circumference than that of the forward Vwheels 184418;

A 'short distance above and in line with v`shaft-or axle 24,'is a beam 27, with the outer ends of which beam are connected the lower 'ends of thesuppo'ting plates 28H28',

uppenends of vfiiv'hich plates Vare connected withfchannelbeanis 12-12. Alith the upper surface of beam 27, at a point equi-distant from .its ends, is connected rigidly the lower endy of the seat Supporting standard 29, upon the upper end of which is the seat 30 for the operator, its position being such as to facilitate the conjoint movement of both feet and the hands in the operation of the machine, as further described.

. The plant chopper supporting and governing devices are located approximately inten mediate the forward and rear ends of the body of the vehicle and consist of vertical guide plates 31-31 connected at their lower ends rigidly with the inner surfaces of the channel beams 12-12 of the body of the vehicle. 0n the inner surface of these guide plates are vertical guide angle bars, 8232, see Fig. 2, spaced equi-distantly apart from each other and the outer vertical edge portions of each guideplate.

The shatt 52 forms the support for the traine 36 upon the plate 34, and upon which shaft the trarne 86 is aftordcd an oscillating or rocking movement.

The plant chopping mechanism consists ot a series ot vertical levers or hars 60-60, 6l--6l, arranged in position in pairs, the pairs being located near the outer vertical portions and in rear of the oscillating trarne 36. These hars 6l-61, which are opposite the lei't hand side of traine, are pivoted by pivots 60" zt a point a little more than onehalt the distance 'from their upper to their lmver ends within the notches 6?-62 in the outer ends ot the respective forward and rear and outwardly and downwardly inclined lower ends (i3-63', of the upwardly extending lever operating bars 641-64 see lligi l0. Both bars 6d, 64, are pivoted tor independent action upon the pivot holt (i5, which passes through the lower portions ot said hars at the angle torined by the outwardly inclined extensions 63-63, the inner end of the pivot bolt being screw-threaded and oxtenoed through the tace plate fili on the oscillating traine 36 at a point about one-third the distance inwardly from the right hand outer edge portion of said trarne immediately above the har el. and secured to a nut 66 in rear et said ita-'n plate 44;, seo Fig. l0.

The levers (5U-60', which are opposite the right hand side ot the oscillating trarne 86, arc pivoted at 69 within the notches in the outwardly and downwardly inclined lower ends 67--67 ot the upwardly extended lever operating` hars 68-68, which are precisely the same as the bars 64-64f- These hars (58-68 are pivoted upon a pivot holt 68X extendingl through the face plate ot the osf-illatingv 'trame 36, about one-thirr the distance inwardly troni the right hand portion oit the said traine 36 and secured in precisely the saine manner to said traine as described ot pivot bolt 65 supporting the hars (S4-64',

seen in Fig. l0.

The upper end oit-the respective pairs of liars ou whO, lil-6l extends upwardly past the rains 57 and 58 to within a short distance of the line of the upper surface of the trarne 63 and portions 70-70 of bars 60-60, extended outwardly at right angles in one direction and the portions l-Tl of the bars (5l-6V extended outwardly at right angles in the opposite directions to the lines ot the vertical surfaces ot the oscillating trarne at which point short portion 70X ot the respective ends ot the portions 7O, 'Tl-l are extended upwardly a short distance. rlhe inner surfaces ot the bars oil-6ej 68--68 are in position to he operated alternately upon by the outer ends ot' the respective Canis 5T and 58. block 72 is secured to the Yface plate t of the oscil leting iframe between the upper ends ot bars 6er-64', (S8-68 which receive the inward thrust of said bars and retain theni in an operative position.

The lower ends oit the respective levers 60-60, 6l-6l, extend downwardly in the direction of the ground and the lower portions 73-73 et levers 60--60 inclined downwardly and inwardly, and also the portions 7er-74 ot the levers 61-61, to torni plant picks, the upper surfaces of these portions ot these picks being inclined downwardly nearly to a point as at 700, these pirlrs being adapted to enter the ground at an angle and to the depth governed by the rise and tall of the plate 3s.

llVith the upper extension 70X ot the outwardly extended portions 70 and 7l' oi: oars 64E and 68, are ronnected the ends ot a coiled spring 75, and with like portions of the extensions 70 and 7l are connected the ends ot a coiled spring Y6. The said out ward extensions YO-70 and le-7l are guided in the 'inward and outward Inoveinents of the upper ends ot' levers (ill-60', (Sl-Gl, within the separate spaces 1oetween the outer and inner guide plates 'T7 and 78, separated hy the blocks 79, at each end these plates being secured to the upper end portion of the oscillating trame '36 and to the tare plate 4st on said traine, through which plates the lolo: k 72 extends.

The adjusting devices for spacing the picks Z3-78 and 74.-74 the desired distance apart in their chopping movements, consist of a vertically movable block in the space 42 between the side plates 38-38 and the faceplate tl of the oscillating trarne 36. With the upper end ot the levers'() and 61 and also the upper end portions of the adjusting bars G8 and 6ft respectively', are pivotally connected the toggle joints 8l and 82 respectively, and with the upper ends of the levers 61-61 and upper end portions of bars 68-68 and 64-64, are pivotally connected the toggle joints or levers 83 and 84 respectively. Operating rods 85 and 86 are pivotally connected-at their upper ends with the respective toggle joints 81 and 83 respectively, and operating rods 87- and 88 f are pivotally connected at their upper ends opening 46 in said face plate 44.

The block 80 is operated by toggle jointed levers 91 and 92, the upper ends of the lever 91 being pivoted to lugs 91X oirblock 80 and which .extends outwardly through the vertical opening in the face plate 44 of the oscillating frame, the lever 92V Vbeing pivoted Yto lugs on face plate 44 below theV opening 45, as seen in Figs. 4 and 5.

With the toggle levers 91 and 92, is pivotally connected the forward end of an operating rod 93, see Figs. 2 and 7, the rear end of which lever extends horizontally rearwardly to a position above the transverse beam 27 and is pivotally connected to one side ofa vertical operating lever 94, at a point the requisite distanceV above the beam 27, the lower end of the lever 94 extendingv downwardly through a transverse opening 95 in said beam 27,-and is pivotally con@ nected with a lug 96 on the lowersurface of said beam.

c, Thenieans for oscillating the frame 36, consists ofV an operating rod 9'! which 1s provided with a U shaped crank arm 98, near theouter end ofrsaid rod, which crank extends upwardly within the notch 99 in the lower portionV of a pivoted bar 100, the outer end 97X of the rod past said crank arm l.entering an opening 102 in the vertically 30V movable plate 34, see Fig. 4. The outer-end of the rodf97Y is journaled in an upright bar 104 on beam 27, then bent upwardly to form a crank arm 104, and with the outer end of said arm is pivotally connectedfthe upper end of a rod 105, the lower end of which lever is pivotallyconnected with the forward end of a foot operated lever 106,

which lever is pivoted between its ends to' upright lugs 107 on the plate 107 secured tothe upper surface of its beam to the right of the support 29 for the seat 30.

VThe means for raising"V and lowering the plate 34 consists ofa crank shaft 108 jour naled at its ends in the' outerk ends of the bars 109, 110, secured at their inner ends to the inner surface of the channelbeam 12 on the left hand side of the frame of the body 10 and which extend'forward and rear respectively of the left hand portions of the said plate 34.

Between thesev bars a U shaped crank arm 111- is formed on the crank shaft 108, which enters the horizontal opening 48 in lower left hand portion of the plate 34.

The forward portion of the crank shaft 108 is bent at right angles immediately forward of the supporting bar 109, and a portion 112 extended inwardly a short distance and provided with a loop 113 .at its outer end. With this loop is connected pivotally the upper end of a rod 114 (see Fig. 3), the lower end of which rod is pivotally connected with the forward end of a long lever bar 115, the rear end of which bar extends beneath beam 27'and rearwardly to a position beneath the rear transverse end member of the frame or body 10, and is pivotally secured to the lower ends of the downwardly extended supporting bars 116, the` upper ends of which bars are rigidly connected with the lower surface of said end member.

A foot lever 117 extends through an opening 118 in the beam 27, its upper end having a fixed stirrup 119 for the foot of the operator, the lower end of the lever being forked and the forked portions pivotally connected with the long lever bar 115.

In order to guide the plate 34 in its upward and downward movements a rod 120 is mounted rotatably in the brackets 121 on the lower rear portion of plate 34, in the outer ends of which rod are toothed wheels 122 which engage with the racks 35 on the guide plates 32, 32, on the uprights 31-31, sce Fig. 8.

The power to operate the machine is communicated from a large cog wheel 124, mounted kon the rear axle 24, between the wheel 26 and the hanger 25. V

lilngjagring with this cog wheel, Vis a small cog wheel 125 mounted on the outer end of a short shaft 126 journaled in the side of the channel beam 12 between its upper and lower flanges. The inner end of shaft 1,26 is journaled in theouter curved end of a bracket 127 secured to the inner side ofthe channel beam'12, and upon said shaft is a bevel gear 128.V rlvhis gear 128 meshes with a bevelgear 129, the shaft 130 supporting which gear extends through the portion of the bracket at right angles to theshaftv 126. Upon the forward portion' of shaft 130 is a universal joint131, and with said joint is connected the rear end of a rotary shaft 132, which extends forwardly through the vertical opening-47 in the plate 34 and Vthence to aposition above the plane of the forward transverse beam 15 and upon said end is a universal joint 133. The joint 133 is connected with a short vshaft 134 journaled in the upper ends of standards 135 and 136, which are mounted iiXedly on` the beam 15 about one-fourth the distance on said beam from the side channel beam 12 toward the side beam 12. Upon shaft 134 is a large gear wheel 137.

Upon the beam 15 to the right oit' the standards 135 and 136, are standards 13S-139, in the upper ends of which is journalcd the end oi a rotary shaft 140 upon which shaft is mounted a small gear 141 which meshes with the large gear 137.

Upon the forward end or shaft 140 is a universal joint 142 and with this joint is connected the forward end ot a power transmitting rotary shaft 142 which extends in the direction of the shaft 52 operating the cams 57 a-nd 58, and also entends within a socket 143 provided with a longitudinal slot 144 through which slot extends a pin 145, which is connected with the shaft 142 permitting a sliding movement of said shaft within the socket 143.

.Vith the rear end of socket 143 is connected a universal joint 146, which is also connected with said rotary shaft 52, carrying the cams 57 and 58.

ln operation, power is applied to the draft beam 11 to draw the vehicle forward in the ield in which the cotton plants extend in rows, these rows being the usual distance for weeding out the plants and gathering the cotton from the boils. The power thus applied, imparts rotation to the wheels 1.8-18 and 26 26', and the draft power on wheel 26 is transmitted through the gear wheel 125 to the bevel gear 128 and 129, thence through shaft 132 tothe large gear wheel 137, thence to the small gear 14 thence to the rotary shafts 142 and 52, and the cams 57 andV 58 on the latter shaft are given rapid rotation and the operating bars E34-64', 68-68, move inwardly and outwardly, each pair alternately, causing a corresponding movement of the levers 60-60, 61-61, and the picks 73-73, 74-7-4. rThe' picks now being ready for chopping out the plants from the rows, and, as seen in Fig. 1, elevated, the various functions are as ollows The operator seated in the seat 30, places the right foot on the foot lever 106, andthe left Jfoot in the stirrup 119 on lever 117, at the same time grasping the upright lever 94 with one hand.

The weight of the plate 34 and the pick operating mechanism is now under control 4 of the foot operated lever 117, and suilicient pressure is applied upon the stirrup 119 to give the proper depth of pick action to the picks.

As the vehicle moves in the direction of the rows, the picks may require closer action to chop out intervening rows of plants, in which case the lever 94 is moved forwardly to force inwardly the toggle jointed levers 91 and 92, which ar-tion ,forces upwardly the block 80 thereby forcing upwardly the toggle joints S1 and S2 and moving the upper ends of levers 60-60, 61--61, outwardly and the picks thereby are drawn closer together. It is observed that the rows ot cotton plants may vary from straight lines and hence it heroines necessary to move the picks from right to left to keep the picks in position as the 'lines oi2 the rows diverge from straight lines. To accomplish this movement, root pressure is applied to the foot lever 106, which rocks the shaft 97 and communica-tes through the crank 93 an oscillating movement to the frame 36, and moving the picks toward the line oidirection oi' the plants.

All of these opera-tions may be simultaneous, compelling' the operator to closely observe the lines of direction of the plants and the action of the picks.

Vhenever the vehicle passes to a high elevation from a lower, the lever 117 is operated to raise the plate 34 and elevate the picks, which action may occur frequently without stopping the vehicle.`

The cam operated bars beine` always under tension of the springs 75 and 76, all shocks to the picks in their chopping action are eliminated, and the leverage on the picks made uniform.

Such rnodiiications of the invention may be employed as are within the scope ot the appended claims.
